Bug 134422

Summary: ftp/vsftpd 421 data timeout (with ssl)
Product: Ports & Packages Reporter: Andreas Schwarz <freebsd.asc>
Component: Individual Port(s)Assignee: Dirk Meyer <dinoex>
Status: Closed FIXED

Description Andreas Schwarz 2009-05-10 15:30:02 UTC 
After upgrading vsftpd from 2.0.7 to 2.1.0 transfers (download or upload 
via ssl) will be interrupted after 300s (idle timeout for data), 
log message "421 Data timeout". It seems that the idle timer is not reset
when packets transmitted via ssl. When setting "data_connection_timeout"
to a high value the problem does not occur (because timeout never reached).

I've tested this behavior with lftp (freebsd) and filezilla (windows),
depending on the client the transmission continues (if the client is able
reconnect).

I'm not sure if this is a general or FreeBSD port specific bug.

Fix: 

Not really a fix, set "data_connection_timeout" (vsfptd.conf) to 
a high value.
How-To-Repeat: Start a down or upload which takes longer then the default idle timeout
and watch the logfile.

Comment 3 Andreas.Schwarz 2009-05-20 22:20:11 UTC 
No, this is another problem (or feature), which is different from the bug I've reported
(for compatibility reasons (with filezilla) require_ssl_reuse=NO is already set). SSL data
connections are working until the timout is reached.

- Send a mail upstream 
this might be a general problem.

Please test the new version 2.1.2
Comment 7 Andreas Schwarz 2009-06-04 02:00:27 UTC 
I made a test with a 1 GB sized testfile, no timeouts anymore. In the changelog 
of vsftp 2.1.1 the fix is described.

 - Fix NASTY regression whereby data transfer timeouts would fire incorrectly under SSL transfers. In addition, the transfer rate caps were not working under SSL transfers. Reported by several people.
